One thing I’ve hoped for on a board capable of running Linux is a battery-backed-up clock so that setting the time at bootup can be done without a network connection or an add-on board. If you ever update this design, I hope you’ll consider adding that. Other than that, this guy looks pretty nifty.

Are there different types of JST connectors? I’ve looked at suppliers on eBay and what they call JST connectors all seem to have the male notch on the connector with the male pins, which is the opposite of the connector the IOIO OTG uses, i.e. its female notch is in the connector with the male pins. A few even appear to have dual notches instead of single. I’m confused as to what I should be looking for if I want to buy the proper JST mating connector for this board from a source other than Sparkfun (no offense, SF).

EDIT: I have subsequently found out that the connector is a “JST-PH” type. Adafruit, for one, sells them.

Here’s my experiences with my Nexus 7 pad. The 7 didn’t detect the IOIO’s Bluetooth dongle, but it found other devices in the room. It’s possible that the IOIO’s Bluetooth dongle is defective (it’s the one Sparkfun supplies, and the LED on it lights up, so I know it’s powered), so I’ll be trying the IOIO with a borrowed Android phone in a few days to see if that phone can talk to it. I hooked up the 7 to the IOIO via USB cable and successfully ran the IOIO Hardware Tester App, and the HelloIOIO app. HOWEVER, in order to get it to work, I had to go to the 7’s Developer Options settings page while the 7 and the IOIO were connected via USB, turn off USB Debugging, then turn USB Debugging back on. It seems this has to be repeated any time the IOIO is powered off then back on.

If I read the Datalogging Datasheet correctly, the logging can be performed at a maximum rate of 1Hz, so if you want to log at 10Hz, you’ll have to hook the device to a computer and log the data there. If that’s the case, you may want to consider the GPS-09133, which is this same receiver without the flash memory.
